SHUTTLE-EXCHANGING DEVICE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 714,665, dated December 1 Application filed March 20,1902. Serial No. 99,15 9. (No model.)

7 t exhausted working shuttle for a full one. In

this device, on the one hand, one shuttle-box is pivotally arranged onthe lay and placed so that it can be conveyed toward a'supplyreceptacle to receive a new or full shuttle, to and, on the other hand, there is provided an adjustable auxiliary box, which while the movable shuttle-box is being filled can take its place for the purpose of temporarily receiving the exhausted shuttle coming out of the other shuttle-box, which is fixed to the lay. By aid of this special or auxiliary box the exhausted shuttle can be caught up safely and then removed from the loom.

In the accompanying drawings, Figure 1 shows, by way of example, a constructional form of a device of this kind applied to a loom, of which only the parts connected with the invention are illustrated. Fig. 2 shows in detail how the shuttle-box pivoted on the 3 5 lay assumes the operative position, it being shown in Fig. 1 adjusted for receiving a new orfull shuttle. Fig. 3 is a side view of Fig.

1. Fig. 41s a vertical section, on an enlarged scale, of the shuttle-box fixed to the lay; and

Figs. 5 and 6 are transverse sections of the shuttle-box pivotally arranged on the lay and the supply-receptacle, respectively.

A, Figs. 1 and 3, is the frame of the loom,

(shown in dotted lines,) and B the lay. The

shuttle-box a, Fig. 1,1eft side, is fixed to the lay, and theshuttlo-box b, Fig. 1, right side,

is pivoted to the lay on an axle c, horizontally placed opposite the open box end, so that it can be vertically adjusted. The supply-receptacle R is arranged on this side of the loom, and in it are placed, one above the another, the full shuttles. The shuttle-box a,

fixed to the lay, has on one side a fixed guidebar 01 and underneath a tongue f, pivoted on a pin eand supported by a spring, .which tongue is connected with a bolt g, extending downward through the lay. In the same vertical plane as this bolt 9 is a bolt h, which usually looks a watched bar t'in the position shown in full lines in Fig. 3. This bar t is linked to an arm j, keyed on the shaft 7t. This shaft bears an elbow-lever qt, which stands under the tractive control of a spring Z and can be brought within the sphere of operation of a rotating cam m. To this elbow-lever is linked a pusher-bar 0, which shogs backward and forward with the lay and is connected by means of a spring 19 and pusher q with a box a This is the aforesaid auxiliary box, which supports below the pivotally-arranged sh uttle-box b. This auxiliary box y is open along its length and can be closed here by the door r, which replaces the side of the box, and is connected with the lay at if by means of the link 5, Figs. 5 and 6. A receiving trough or tray u is fixed to the lay.

As mentioned above, the full shuttles in the supply-receptacle R lie one above the other. These shuttles are of the construction described in Letters Patent No. 648,5l7,dated May 1, 1900. The lowest one is gripped at its ends by two arms 1 pivoted at 41: on the side walls of the receptacle R and rests in the notch w thereof, Fig. 6. vided with a downwardly-projecting pnsherw.

In order to assure the straight and horizontal position of the shuttle, the shuttle-box b, pivotally placed on the lay,'is provided with the movable tongue .2, which at the top has a cover-plate .2", which projects beyond the tongue and partially closes the top opening of the box. The tongue .2 when the shuttle-box I) is adjusted vertically can be drawn back by means of a guide-roller it, guided These arms are proalong a sloping bar 08', so that the cover-plate 2 does not impede the shuttles falling out of the supply-receptacle R. The guide-rollertt' is kept pressed in the usual manner against the bar w by means of a spring. This detail, however,for the sake of clearness,is not shown in the drawings.

In order to effect the exchange of the shuttle when the weft-thread in the working sh uttle is almost exhausted, it is assumed that every shuttle is provided with a pin a, Fig. 4, under spring control and passing through the side wall of the shuttle. This means is well known, and as long as there is sufficient weft-thread on the spool the pin a is held drawn back by the Weft-thread in the shuttle; but when the thread is nearly used up the pin is released in order to project out of the side wall of the shuttle.

The operation of the apparatus described above is as follows: As soon as the operatingpin ct of the working shuttle is released, as just described, by the weft-thread becoming exhausted, and projects out of the side wall of the shuttle, it presses, on passing into the shuttle-box a fixed to the lay, the pointed tonguefa little down, and with it the pin g. By the continuation of the movement of the lay toward the bolt 7b, the pin 9 strikes against the bolt 72 which lies in its plane of movement and presses it back, so that the ratchetbar 2', which up to now was held by this bolt h, is released. The elbow-lever n is then drawn by the spring Z against the cam m, Fig. 3, dotted lines, and the pusher-bar 0 is raised, so that the auxiliary box 1 is lifted up, and consequently the shuttle-box b, Fig. 5, pivotally arranged on the lay, is moved up. At the same time the grips o are turned by means of the pusher m so that the shuttle hitherto retained by them can fall into the shuttle-box Z) underneath the supply-receptacle R, whereby the shuttle which is now lowest in the supply-receptacle is supported by a projection "v of the grips. While the raised shuttle-box b is being supplied with a new shuttle, the auxiliary box y assumes the operating position of the box b. This auxiliary box consequently catches the exhausted shuttle coming out of the shuttle-box a. The door 0' is then in the closed posit-ion in order to return the caught shuttle in the box y.

After the exhausted shuttle has quitted the shuttle-box ct,fixed to the lay,and the movable tongue f becomes free the striking-pin g and bolt 7t pass back into their position of rest, the cam m by means of the levers j and 01 moves down the bars 2' and 0, and the ratchetbar t is again locked by the bolt h. The shuttle-box b has been lowered thereby, and the door r of the auxiliary box y opened, and the shuttle caught in the latter can, owing to the shaking due to the motion of the loom, be cast into the tray to, Fig. 6, which delivers it to a collecting-receptacle. The tongue 2 and cover-plate a have also returned to their original positions. The shuttle-box Z), pivoted to the lay, now resumes its operative position, Figs. 2 and 6, and the gripping-arms a; hold in their notches w the undermost shuttle of the supply, in readiness for the next exchange of shuttles.

At the same time as the shuttle-exchange movement of the shuttle-box b the nearly-exhausted weft-thread of the shuttle to be changed can be automatically out 01f at the selvage of the fabric in the usual manner, so that the shuttle can fall out of the loom, drawing its cut-off thread end after it. This device for cutting off the thread is not illustrated in the drawings for the sake of clearness, as it is already known.

What we claim is- 1. In a loom, a device for automatically exchanging the shuttles, comprising in combination with the lay a shuttle-box on one side thereof and fixed thereto and on the other side of the lay a pivotally-arranged shuttlebox, a receptacle for holding a supply of full shuttles, an adjustable auxiliary box for catching the exhausted shuttle to be exchanged, an automatic mechanism for conveying the shuttle-box pivoted to the lay'toward the supply-receptacle to receive a new shuttle and for moving said auxiliary box into the operative position of said movable shuttle-box, in order to catch the exhausted shuttle coming out of the shuttle-box fixed to the lay, and means for effecting the operation of this mechanism when the weft-thread of the working shuttle is exhausted.

2. In a loom, a device for automatically exchanging the shuttles, comprising in combination with the lay on one side a shuttle-box fixed thereto and on the other side a verti- (sally-adjustable shuttle-box on a horizontal pivot placed opposite the open box end, a receptacle higher than the latter shuttle-box for receiving, a supply of full shuttles, an auxiliary box underneath the vertically-adjustable shuttle-box and movable with it for temporarily catching the exhausted shuttle, an automatic mechanism for conveying the vertically-adjustable sh uttle-box toward the supply-receptacle and the auxiliary box into the operative position thereof and means for effecting the operation of this mechanism when the Weft-thread of the shuttle in use is exhausted.

3. In a loom, a device for automatically exchanging the shuttles, comprising in combination with the lay a shuttle-box on one side thereof and fixed thereto and on the other side of the lay a pivotally-arranged shuttlebox, a shuttle-supply receptacle higher than the latter shuttle-box, an auxiliary box, underneath the said pivotally-arranged shuttlebox and movable with it for temporarily catching the exhausted shuttle to be exchanged, an operative bar for conveying the pivotallyarranged shuttle-box toward the supply-receptacle and the auxiliary box into the operative position thereof, which bar is controlled by a rotating cam, a mechanism for usually locking saidbar in its place of rest, and means for releasing this locking mechanism automatically whenthe weftthread in the shuttle in use is exhausted in order to free the said operative bar.

4. In a loom, a device for automatically exchanging the shuttles, comprising in combi; nation with the lay and a shuttle-supply receptacle, an adjustable auxiliary box which is temporarily brought into the normal position of the pivotally-placed sh uttle-box when the shuttles are exchanged, an operating-bar for adjusting said shuttle-box in combination with a spring and a cam, a ratchet-bar coupled with this operating-bar, a bolt for the ratchet-bar, a disengaging-pin on the fixed shuttle-box, and a device on the shuttle by means of which when the weft-thread is exhausted the disengaging-pin can be brought within the reach of said bolt whereby this latter can then be disengaged from the ratchetbar by the subsequent movement of the lay.

5. In a loom, a device for automatically exchanging the shuttles, comprising in combination with the lay a shuttle-box on one side thereof and fixed thereto and on the other side of the lay a pivotally-arranged shuttlebox and a shuttle-supply receptacle higher than the latter sh uttle box, an auxiliary box underneath the said pivotally-arranged shuttle-box and movable with it for temporarily catching the exhausted shuttle to be exchanged, means for conveying the said pivoted shuttle-box toward the supply-receptacle and the auxiliary box into the operative position thereof when theaveft-thread is exhausted, a movable closing-piece for partially closing the top opening of the pivoted shuttle-box, and a means for drawing back said piece when the shuttle-box moves into the filling position, to enable the full shuttle to enter unimpeded.

6. In a loom, a device for automatically ex changing the shuttles, comprising in combination with the lay and a shuttle'supply receptacle a shuttle-box pivotally arrangedon the lay, an adjustableauxiliary box which has a lateral aperture, and when the shuttles are being exchanged is brought temporarily into the position of said pivoted shuttle-box, a device for adjusting the pivoted shuttlebox and the auxiliary box for the purpose of enabling the shuttles to be exchanged, and a door for closing the lateral aperture of the auxiliary box,.said door being connected with a part of the lay so that when the movable shuttle-box is conveyed into the filling position it can be automatically closed, and when it moves back it can be opened again to let the caught empty shuttle fall out.

7. In a loom, a device for automatically exchanging the shuttles, comprising in combi' nation with the lay a shuttle-box on one side thereof and fixed thereto and on the other side of the lay a pivotally-arranged shuttlebox and a shuttle-supply receptacle higher than the latter shuttle-box, an auxiliary box underneath the said pivotally-arranged shuttle-box and movable with it for temporarily catching the exhausted shuttle to be exchanged, means for conveying the said pivoted shuttle-box toward the supply-receptacle and the auxiliary box into the operative position thereof, when the weft-thread is exhausted, the said shuttle-supply receptacle being on one at least of its front ends provided with a pivotallymounted grip-arm which holds the lowest of the shuttles in the receptacle and can be turned when the movable shuttle-box is conveyed into the filling position, so that the shuttle it hitherto held is allowed to drop and the said arm being adapted to support thereby the succeeding shuttle of the supply in order to retain the same. p
